40A Solid State Relay - 3-to-32V DC Controlled - 5-to-220V DC Load
DC Solid State Relay 40A — 3–32V DC Control, 5–220V DC Output
Reliable DC-DC Switching for DIY, Automotive, and Electronics Projects
This DC solid state relay makes it easy to switch high-power DC loads using a low-voltage control signal. It’s quiet, fast, and has no moving parts—ideal for applications where a mechanical relay would wear out or create electrical noise.
What It Is
You’re looking at a single unit: 1PCS DC Solid State Relay 40A from Vetco, model VUPN1127. It’s a DC-to-DC solid state relay with an input control range of 3–32V DC and an output switching range of 5–220V DC, rated up to 40A (single phase DC).
Why Use a DC Solid State Relay?
Solid state relays (SSR) provide fast, silent switching with excellent durability. Compared to mechanical relays, SSRs offer reduced arcing, improved reliability, and better performance for frequent on/off cycles—great for LED lighting, DC heaters, motors, battery systems, solar projects, CNC/3D printer mods, and hobby electronics.
Key Features
- DC-DC SSR (VUPN1127) for clean, silent switching
- Wide control voltage: 3–32V DC (logic-friendly)
- Wide load range: 5–220V DC output
- High current capacity: up to 40A (single phase DC)
- Optically isolated control for safer interfacing with microcontrollers and PLCs
- Solid-state design: no contacts to wear out
Technical Specifications
- Type: DC Solid State Relay (DC-input to DC-output)
- Brand: Vetco
- Model: VUPN1127
- Control (Input) Voltage: 3–32V DC
- Load (Output) Voltage: 5–220V DC
- Rated Load Current: 40A
- Phase: Single phase (DC)
- Quantity: 1 piece (1PCS)
Typical Uses
Switch and control DC heaters, LED arrays, DC motors, power resistors, and other DC loads within the specified voltage/current range—using a simple 3–32V DC control signal from a microcontroller, power supply, or PLC.
Quick Tips
- Verify your load current and DC voltage fall within the relay’s 40A / 5–220V DC output ratings.
- Observe correct polarity and wiring practices for both control and load sides.
- As with most high-current SSR applications, ensure adequate thermal management appropriate to your load and duty cycle.
